The Omega Speedmaster with reference ST 105.012 (made from 1964 to 1968) is the first Speedmaster with the new case that is made to protect the crown and push-buttons. The reference ST 145.012 is also the reference that was worn during the first Apollo missions and in particular the Apollo XI mission that actually led to the landing on the moon. Neil Armstrong was equipped with an ST 105.012. This reference is, therefore, the Speedmaster that is worn on the moon. Incidentally, it is unclear which reference Buzz Aldrin bore. Michael Collins, who stayed in the shuttle during the mission, wore a reference ST 145.012.
The reference of the Speedmaster that we further describe here is ST 105.012-65. This watch was produced around 1966. The dial, hands, and bezel are original and belong to the watch. The timepiece is, of course, the caliber 321 of the second generation.
As mentioned, this reference is very important for the history of the Speedmaster. In good and original condition, these watches are increasingly difficult to find. We as Speedmaster enthusiasts are happy with this model in our collection. It will certainly appeal to the Omega enthusiast and collector.
